There is an asymmetry in ttusb_dec_init_usb()-ttusb_init_rc() and ttusb_dec_exit_usb()-ttusb_dec_exit_rc() in terms of resources allocated-deallocated. irq_urb and irq_buffer are allocated in ttusb_dec_init_usb(), while they are deallocated in ttusb_dec_exit_rc(). As a result there is a leak of them in ttusb_dec_probe(). The patch fixes the asymmetry and a leak on a failure path in ttusb_dec_init_usb(). By the way, it - removes usage of -1 as a custom error code, - replaces GFP_ATOMIC by GFP_KERNEL in usb_alloc_coherent() in ttusb_dec_init_usb() as soon as all other memory allocation done with GFP_KERNEL; - refactors ttusb_dec_boot_dsp() in an equivalent way except for returning 0 instead of 1 if ttusb_dec_boot_dsp() succeed in (!mode) branch.
